Thinkorswim has DDE capability and it's free if you have an account with them. Don't know the limit on the number of tickers, but you can ask them, If you can stream option chains into excel with greeks, IVs and etc then I'm sure it can handle OHLC for stocks.

I guess it all depends on what you do whith the quotes that determines which route you should go. (Standalone data feed or broker-based feed.)
